public class PluginLoader
extends Object

OpenWebBeans plugins are used to extend 'core' functionality of the injection mechanism with functionality of other frameworks.

Core functionality are all parts which are available in a standard JDK-1.5 SE runtime. Extended functionality are things like JPA, JSF, EJB etc.

The plugin mechanism is based on the ServiceProvider functionality http://java.sun.com/javase/6/docs/technotes/guides/jar/jar.html#Service%20Provider. A jar containing an OWB plugin has to expose itself in the file META-INF/services/org.apache.webbeans.plugins.OpenWebBeansPlugin
